Abstract

A compact disc coupled to a wireless communication device comprises the disc with a metalized outer portion, a wireless communication chip and a pair of tabs. The first tab may capacitively couple the wireless communication chip to the metalized portion of the disc. The second tab may be positioned in an inner portion of the disc with a gap delimited by the metalized portion and the second tab. A slot antenna is thus formed through which the wireless communication device may communicate. Wireless communication chip allows disc to be interrogated and identified for a variety of purposes, including, but not limited to security, advertising and promotion, and issuing of related coupons to customers for subsequent purchases.

Claims

1. A disc having data stored thereon coupled to a wireless communication device.

2. The disc of claim 1, wherein said disc comprises an outer metalized portion.

3. The disc of claim 2, wherein said wireless communication device comprises:

a wireless communication chip;

a first tab positioned on said outer metalized portion;

a second tab spaced from said outer metalized portion by a gap with said wireless communication chip positioned between said first tab and said second tab; and

a stub extending from said second tab across said gap.

4. The disc of claim 1, wherein said disc is a compact disc.

5. The disc of claim 1, wherein said disc is a mini disc.

6. The disc of claim 1, wherein said disc is a DVD.

7. The disc of claim 3, wherein said second tab forms an annulus positioned over an inner portion of the disc.

8. The disc of claim 3, wherein said first tab capacitively couples to said outer metalized portion.
